Claims.

This invention relates to divan beds and has for its object to providean improved structure of this character.

The-known divan beds with reversible frame have the defect that theirreversing device is too complicated and not sufciently strong. For thisreason the handling of such divan beds when converting them from thedivan form into the bed form is dicult and v requires considerablestrength and skill. In many cases the upholstery is compressed at thesupporting points during the use as bed, so that at those points theupholstery becomes shabby or even damaged. In the case of divan bedswhich have rollers for supporting the frame the movement of the rollersis respon`- sible for undesirable noisiness during conversion.

According to the invention these defects are eliminated by providing thereversible frame at the ends of opposite sides with supporting rollersor pins adapted to rest on the underirame when the divan bed is in use,axles of rotation being provided between said supporting journals orrollers, whereby the reversible frame is rotatably connected to theunderframe.

In the accompanying drawing one embodiment of the invention isdiagrammatically illustrated by Way of example.

Fig. 1 is a part sectional view of the underrame showing the reversibleframe with chain dotted lines in the position of rest and in the courseof reversal,

Fig. 2 is a section through the axle of rotation of the reversibleframe, at right angles to the sectional plane in Fig. 1,

Fig. 3 is a view similar to Fig. 2, showing the reversible frame in itsvertical position,

Fig. 4 is a perspective part sectional view of the divan bed, when usedas bed,

Fig. 5 is a plan view of the divan bed, when used as bed in closedposition,

Fig. 6 is a perspective view of the divan bed, one side closed withbedding, the right side without bedding. Referring to the drawing, aisthe underframe,

b the reversible frame which is fitted on one side as a divan and on theother side as a bed with mattress and bedding. The reversible frame bhas in the vicinity of the opposite narrow sides rollers or journals cwhereby it rests on laterally coniined bearing shoulders d of theunderframe, so that it can perform no lateral movements in thisposition. The bearing shoulders d are connected together at the narrowsides of the underl,frame by respective curved, preferably circular1936, Serial No. 71,086

arc shaped guide paths e for the rollers or journals.Y Furthermore, thereversible frame b has respective axles of rotation j at the oppositenarrow sides which are in engagement with respective levers gl rockableby pivoting them at l on the underframe. Each of said levers g has nearthe axle f an abutment h, for lifting and holding a cover flap z' forthe reversing mechanism. The lever g is a bell crank lever pivoted atland carries at one end the bearing for the axle f of the reversibleframe b and has connected to its other end a tension spring lc in such amanner that this spring lc forms with the lever g a very small acuteangle in the position of use of the reversible frame b, said angle beingincreased when the reversible frame b is lifted, until the parts occupythe position shown dotted in Fig. 1, in which the spring lc acts uponthe bell crank lever g with a comparatively large leverage and holdssame in thereversing position. 'I'he underframe a has an abutment mwhereby the movement of the lever g under the action of the spring k islimited in the reversing position. The reversible frame b has foldablehead and foot rests n at its narrow sides which are hinged to thereversible `frame b by means of bent ends or elbows. Owing to the bentends o and the curved formation of the head and foot rests n same form ahollow space, when folded down, for the reception of the mattress andthe bedding. Said rests may be attached to the reversible frame by meansof thongs or straps for holding the mattress and bedding firmly inposition when the frame is bed side down. It is preferred to dispose theaxles of rotation f centrally of the narrow sides of the reversibleframe and the pivot point of the levers a laterally of said axles.

In the position of use the reversible frame b rests with its rollers orjournals on the bearing shoulders d of the underframe a. For reversalone longitudinal side of the reversible frame b is slightly lifted,whereby the axles of rotation f of the reversible frame b are caused tomove upwards and the leversg are rocked to such an eX- tent that thesprings 1c promote the movement of the reversible frame b into thereversing position and resiliently hold same in that positio'n. In thereversing position the reversible frame b is rotated around the axispassing through the axles of rotation f, one pair of the supportingrollers or journals c being guided on the paths e, untill the reversibleframe b is turned through The reversible frame is now pressed downagainst the action of the springs lc and the lever y is returned intoits original position, in which the frame is unable to rise on its ownaccord under the action of the springs lc which act upon the levers gunder a very small acute angle. The

reversible frame then will again rest on the bearing shoulders d of theunderframe a with its rollers or journals c.

The space between the reversible frame b and the underframe a, necessaryfor the play of the reversible gear y, Z, m, lc is covered above byilaps i, which at the conversion of the reversible frame b are liftedand held by the abutment h, arranged on the lever g,.ti1l the reversibleframe is moved from the reversible position into the respective positionof rest. 'Ille end Walls n are connected with the foot rests of thereversible frame by stuff-parts p' or the like, Vwhereby the bedding isprevented from getting into the space for the reversible gear f, y, h,l, m, n. When the reversible frame b is used as a bed the head and footrests 11 lean with their under ends upon the closed flaps i. Thefoldable head and foot rests n cooperate with the reversible gear f, g',h, as it separates the bedding from the gear and its space and permitsrotation of the reversible frame b with the bedding and holding thebedding on the underside of the frame b without touching between theunderframe a and the gearing f, g, h, Z, m, lc on the one side and thebedding on the other side. Thus' it is believed, the combination of themeans for rotation of the reversible frame b with the holding means forthe bedding is in no aggregation,
